This weapon is suitable for clearing out narrow corridors or corners. Because of the weapon's splash damage, the concussion rifle should be fired and treated like a rocket launcher, though it has considerably less firepower. It does not fare well in wide open terrain and should instead be used as a "corridor sweeper".
The weapon can sometimes utilize objects around it to a more lethal effect than the bolts it fires. A small crate shot at from close range can be launched fast enough to kill any enemies within a relatively short range, thought the exact distance depends on its trajectory. The kinetic energy from its blasts can also be used to push an opponent off a tall structure or cliff to his death.
